loosing content after <–more–> when editing using xmlrpc

I discovered that if you edit a post using xmlrpc using Microsoft Office 2007 or OpenOffice.org you loose all the text after <!–more–> tag.

In fact the text is not even retrieved an when you save the post you just loose the main part of the article.

Initially I suspected a bug in Office 2007 but after testing with OpenOffice.org the problem did reproduced.
